nginx 0.1.36 *) Change: if the request header has duplicate the "Host", "Connection", "Content-Length", or "Authorization" lines, then nginx now returns the 400 error. *) Change: the "post_accept_timeout" directive was canceled. *) Feature: the "default", "af=", "bl=", "deferred", and "bind" parameters of the "listen" directive. *) Feature: the FreeBSD accept filters support. *) Feature: the Linux TCP_DEFER_ACCEPT support. *) Bugfix: the ngx_http_autoindex_module did not support the file names in UTF-8. *) Bugfix: the new log file can be rotated by the -USR1 signal only if the reconfiguration by the -HUP signal was made twice.
